WHlFFLETREE-HOOK.

SPECIFICATION forming part of Letters Patent No. 233,639, dated October 26, 1880.

Application filed September 10, 1880.

T 0 all :whmn it may concern:

Be it known that I, ADoLPH PFEIFFER, of Neenah, in the county of Winnebago and State of Wisconsin, have invented certain new and useful Improvements in Vhiffletree- Hooks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

h'ly invention relates to a whiffletree, either single or attached to a double-tree; and the novelty consists in the construction and arrangement of parts as will be more fully hereinafter set forth, and specifically pointed out in the claims.

' The object of the invention is to provide a device by which the driver may detach from the vehicle a runaway, vicious, or an uncontrollable animal at will, by releasing such animal from the vehicle.

In carrying out my invention I employ an eyebolt or cockeye having socket, in which operates a locking-bolt, which secures the eye of the draft-trace or tug within the cockeye.

The cockeye is formed with a horizontal slot, which receives a threaded thumb -piu which screws into the locking-bolt, anda spiral spring operates between thehead of said pin and the leather or other flexible plate resting on the surface of the cockeye immediately surrounding the slot, to hold with a constant iorce said strap or plate, a cord from which passes longitudinally along the whiffietree and through an eyebolt near the center thereof from one side, forms a loop, and passes through a similar eyebolt upon the opposite side of the center of the whiffietree, and is similarly attached upon the other end.

The spiral spring in the thumb-pin serves to hold with a constant force the locking-bolt in position; but a supplementary cord, which leads backward and is secured to the loop formed by the plate-cord between the eyebolts upon the whiffletree, allows the driver to overcome the force of the spring and withdraw the (No model.)

locking-bolt, which releases the draft and the animal.

The interposition of the plate or strap of leather between the spiral spring of the pin and the cockeye prevents rattling of the parts, besides operating to hold the same firmly at any desired point.

In the accompanying drawings, Figure 1 is a plan view; Fig. 2/, a partial vertical section, and Fig. 3 a modification.

Referring to the drawings, A represents the whiffletree, and B the cockeyc, cast in one piece, and having a socket, B, a slot, 11, a recess, B and a socket, H, as shown. The sockets B B are upon opposite sides of the recess B and serve to receive the sliding or reciprocating bolt 0. This boltpasses through an eye in the trace or tug, and serves to lock it until the locking-bolt is withdrawn by the driver.

D represents a screw-pin which reciprocates in a slot, 1), in the cockeye, and which is secured by its thread to the locking-bolt C. It is embraced by the plate E, to which is secured, at e, a rope, cord,or strap which passes through eyes G and forms loop H, as shown. A cord, 00, leads back to the driver within convenient reaching distance.

A modification of my invention is shown in Fig. 3, wherein the locking-bolt is held, by the construction of the cockeye, away from the 1011- gitud'inal plane of the center of the whiffletree.

Between the headed pin and the plate or strap E is a spiral spring, which bears with sufficient force between the inner surface of the head of the pin D to hold the bolt 0 in a locked position.

If desired, the cockeye may be made in two parts, joined or screwed together at the end of the socket.

What I claim as new is-- 1. The combination, with the cockeye having recess B slot 1), and sockets B B of the locking-bolt G, screw-threaded pin D, passing through the plate E and slot 1), and secured to the bolt 0, plate E, and spring K, interposed between the head of said pin and the plate, substantially as and for the purposes described.

The combination, with the coekeye hav- In testimony that I claim the foregoing I ing recess 3, slot 1), and sockets B 13", of the have hereunto set my hand and seal this 4th 10 lockingb01t O, screw-threaded pin D, passing day of August, 1880. through the plate E and slot 1), and secured to 5 the bolt 0, plate E, spring K, interposed be- ADOLPH PFEIFFER' tween the head of pin D and plate E, staples Witnesses: G, cord or strap H, and cord or, as shown and L.
